Let the wedding planning begin!
But she is giving some details. Read on to find out what she just told us about the dress, the date and Kate Middleton...
"I just started ripping out pictures in magazines," Cavallari said at last night's Hollywood premiere of Kate Hudson's new romantic comedy, Something Borrowed. "I know that I want my dress to be a little bit tighter on the top and then kind of go out."
So like a big poofy princess dress? "No, because I'm so little, a big dress would just swallow me," she said.
As for the bridal party, she revealed, "I want black bridesmaids dresses."
The nuptials will likely take place in Chicago, where Cavallari's mom lives and most of Cutler's family is from. "It will probably be next spring because of the football season," she said. "It would either have to be in the next couple months or next spring so about in a year."
And she wouldn't mind talking to newly wedded Kate Middleton. "She could probably give me some great advice," Cavallari laughed. "She had the biggest wedding of the century."
Cutler recently popped the question during a vacation in Cabo San Lucas. "I'll tell you he did get on a knee and it was very romantic and very sweet," she dished. "I had tears in my eyes."
Cavallari admits the proposal wasn't a total surprise. "I had a little bit of an idea," she said. "I thought it would be in Cabo. I didn't know when exactly in Cabo it would be."
The couple began dating back in August. "I couldn't be happier in my relationship," Cavallai beamed. "Jay is just such a great guy. We have such a great relationship."
As for the ring. "It's a little big," laughed the bride-to-be, "I need to get it sized. It's falling off."
